Scaling regimes of active turbulence with external dissipation
Berta Martínez-Prat, Ricard Alert, Fanlong Meng +5
Active fluids exhibit complex turbulent-like flows at low Reynolds number. Recent work predicted that 2d active nematic turbulence follows universal scaling laws. However, experime…
Magnetic microswimmers exhibit Bose-Einstein-like condensation
Fanlong Meng, Daiki Matsunaga, Benoît Mahault +1
We study an active matter system comprised of magnetic microswimmers confined in a microfluidic channel and show that it exhibits a new type of self-organized behavior. Combining a…
Modelling Mullins Effect Induced by Chain Delamination and Reattachment
Daoyuan Qian, Fanlong Meng
We propose a continuum theory to model the Mullins effect, which is ubiquitously observed in polymer composites. In the theory, the softening of the materials during the stretching…
Designing metachronal waves of cilia
Fanlong Meng, Rachel R. Bennett, Nariya Uchida +1
On surfaces with many motile cilia, beats of the individual cilia coordinate to form metachronal waves. We present a theoretical framework that connects the dynamics of an individu…
Degenerate states, emergent dynamics and fluid mixing by magnetic rotors
Takuma Kawai, Daiki Matsunaga, Fanlong Meng +2
We investigate the collective motion of magnetic rotors suspended in a viscous fluid under an uniform rotating magnetic field. The rotors are positioned on a square lattice, and lo…
Focusing and sorting of ellipsoidal magnetic particles in microchannels
Daiki Matsunaga, Fanlong Meng, Andreas Zoettl +2
We present a simple method to control the position of ellipsoidal magnetic particles in microchannel Poiseuille flow using a static uniform magnetic field. The magnetic field is ut…
